Honda Pilot key fob problems

Filed Aug 19, 2026 · Electrical · NJ

My 2019 honda pilot ex-l was stolen from our driveway in jersey city, nj on or about july 16, 2026. The vehicle was locked. Both factory key fobs remained in my possession and were inside my residence at the time. No window was broken and no glass was found at the scene, indicating the vehicle was opened and started electronically rather than by forced entry or mechanical bypass. We have a video recording of the incident captured by our house security camera. The vehicle has not been recovered. A police report was filed with the jersey city police department [26-140624]. This vehicle is equipped with honda smart entry and push-button start. Security researchers have publicly documented a rolling-code vulnerability in honda remote keyless entry systems (cve-2022-27254, known as "rolling-pwn") reported to affect honda vehicles from model years 2012 through 2022, which includes this vehicle. Honda has publicly acknowledged that remote keyless commands can be mimicked, but has stated it has no plan to update older vehicles. No recall, software update, or owner remedy has been offered for this vehicle. Police departments in northern new jersey, including newark, have issued public warnings in 2026 that thieves are using electronic devices to capture or relay key fob signals to steal late-model honda vehicles. The pattern described in those warnings matches the circumstances of this theft. I am reporting this as a potential safety and security defect in the vehicle's electronic immobilizer and keyless entry system. A vehicle that can be opened and driven away without the key present defeats the purpose of the anti-theft immobilizer and creates risk beyond property loss, including the operation of the vehicle by an unauthorized and unidentified driver on public roads. I request that the federal safety agency investigate whether a defect investigation is warranted for honda keyless entry and immobilizer systems in these model years.

Honda issued Service Bulletin 20-117 regarding a Warranty Extension for the 2016–2017 Pilot and 2017 Ridgeline addressing a Keyless Start System Error with DTC B12C5. Following an the federal safety agency investigation, Honda extended warranty coverage to 9 years or 125,000 miles under this bulletin. My 2016 Honda Pilot currently has 107,000 miles and is only six months past the nine-year time limit. Earlier this year, the Keyless Start System warning indicator began appearing intermittently—illuminating for a few seconds before disappearing for days or weeks. Recently, the warning began to stay on continuously. Per Honda’s initial guidance, I replaced the key fob battery and even swapped fobs with my wife, but the issue persisted. On October 16th, I brought the vehicle to Honda of Chantilly, where technicians diagnosed a faulty start/stop button requiring replacement. I then opened case #15920037 with Honda, but they declined to cover or reimburse the repair, despite it being a known defect covered under the extended warranty for others. I respectfully request that the federal safety agency assist in having Honda honor the warranty extension for this documented issue, given the close proximity to the coverage limit and the long-standing nature of the defect.

I am reporting a recurring “Keyless Start System Problem” warning on my 2017 Honda Pilot. This is a known and widespread issue affecting 2016–2017 Honda Pilot models, as acknowledged by Honda in Service Bulletin 20-117, which identifies a defect in the push-button start/stop switch assembly. In my vehicle, the warning appears intermittently, and the engine sometimes fails to start or requires multiple attempts to engage the ignition. This is a serious reliability and safety concern, as the vehicle may not start when needed, potentially leaving drivers stranded or unable to respond in emergencies. Although Honda recognizes the defect in their service bulletin, they have not issued an official recall and refuse to repair or replace the part outside of warranty coverage. Many owners are being forced to pay out-of-pocket for a clearly documented manufacturer fault. I respectfully request that the federal safety agency investigate this issue and consider requiring Honda to issue a recall or provide a no-cost remedy for all affected 2016–2017 Honda Pilot vehicles. Additional details: •Model: Honda Pilot •Year: 2017 •Issue: “Keyless Start System Problem” warning, intermittent failure to start

After fixing a few of the recalls, the alarm on my 2017 Honda Pilot would start going off at random times. After several attempted fixes - replacing the key fob batteries, replacing the car battery - the issue has persisted and we noticed a clicking noise coming from the dash. Essentially the car would attempt to turn on without anyone near it. There are no warning messages present. Thus far, it has not replicated while driving. We have just taken the issue to the Honda dealer and they have come back with a $1400 charge to replace the Smart Power Control Module. In researching the issue, I've seen a number of owners have this issue with 2016-2018 Pilots and even seen some complaints in your database.

Continued from previous submitted complaint: Driver window will not stop when trying to stop it forcibly with hand. I was told that the window will not stop until the window is almost closed at the top. Hope a 4 year old's arm isn't in it. Front passenger window will raise 1/4 of the way up, then fall back down and rock on it's cradle. I took a video of it happening but Charlie's Honda, Augusta, Maine did not want to see it. The Key Fob is a nightmare. It tells me it won’t lock because key is in vehicle. The key is in my pocket as I walk away. It also tells me that “No Key Detected” I’m sitting in the driver’s seat with the vehicle’s engine physically running. Rear Hatch will not open when physically pushing release button. Much more reported but Charlie's Honda has an excuse ready at all times. I bought this Pilot on 10/02/2023 and have nothing but problems with it up to date 6/20/2025. Previous owners kept it for 4 months then traded because they felt very unsafe in it. Which I didn't know this info until 6-15-2025

The auto idle-stop feature in my Honda Pilot prevented from starting the engine again. It is available for inspection upon request. I was at the stop light with the idle-stop feature enabled and when it was time for me to start driving again, the car would not start. The car turned off completely and a lot of the lights including the battery light turned on and a message stating to bring the key fob close to the start button came on. The battery has been changed within a year since I mentioned this problem to the dealership when I brought it in for an oil change. They determined that they had to change the battery. Clearly this did not solve the issue. When this happened today, I was driving on [XXX] which is a highway with a lot of traffic. Since I was unable to move forward, I backed up the traffic coming behind me. The problem has not been produced or confirmed by the dealer since this happened today. The component has not been inspected by the manufacturer even though I have brought it up to their attention, police, or insurance representatives. No warning lamps, messages or other symptoms of the problem prior to the failure have appeared. This is the first time that the car has completely failed to re-start. In the past, it has struggled to start, but it makes it happen. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Door locks do not respond. I will use the driver unlock button on the driver door panel, or sometimes by key fob, and the driver door will unlock, but the passenger (with less frequency than rear) and rear doors will remain locked. Sometimes they will all work. Generallly it’s the rear doors. Very intermittent and hard to reproduce. They tend to stay locked until I power the vehicle off.

Every week or two, sometimes multiple times in same week, the 2020 honda pilot would turn on randomly in accessory mode where headlights would come on and/or infotainment/radio would come up, or alarm/horns would go on by themselves. Often in the middle of the night when car was in a garage. Sometimes during the day. New vechicle battery was replaced 2 months earlier. Batterries in key fobs were replace but issue continued. Honda dealership diagnosed it as keyless access unit letting voltage through transistor waking ignition switch and recommended replacement of keyless access unit. 2020 pilot was 4 years old with 55,832 miles. Appears to be a common issue/complaint on online forums with replacement of remote keyless access control unit. Dealership replaced unit 19 days ago.
